2.5.1. Difference from Control test
This test was carried out by 33 assessors (15 male and 18 female between 20 and 60 years old), who had been selected by their sensitivity to taste, according to ISO/DIS 3972/1979 (ISO, 1990). All subjects were familiar with the test format and the meaning of the scale. The test objective was to determine whether a difference exists between the FPBFB sample and control (fresh French bread) regarding appearance, tactile by direct touch and mouthfeel, and to estimate the size of
any such differences (five-point scale ranged from ‘extreme difference’ to ‘no difference’). Each panelist was presented with one control and two test samples without informing them that one of the samples is control. Sample scores were evaluated by comparing with the results obtained from blind control.
